The following four numbers are listed in ascending order: 7, x, 24, y. the median of the four numbers is 18 and the mean is 61. Find y x=12

Answer 1

If the median is 18
then 18 is halfway between x and 24
18 = (x+24)/2
x+24 = 36
x = 12
so we have
7 , 12 , 24 , y

well 61 = 7+12+24+y /4
244 = 43 + y
y = 201
